Right now i'm reading "negima" That has to be one of my favorites. I also like Jellyfish princess, the anime, but haven't checked out the manga. That may be my next one. Other mangas .... I liked "Fruits Basket." I watched more animes than I have read manga. I also like the "mermaid saga."

Mine favorites must be:Naruto - No reason to explain, enough reasons out there.Nanatsu no Tazai - Very new manga which is very different, and I like the main charachter a lot.Fairy Tail - I dislike the anime over the manga, because the anime is so non serious. Shingeki no Kyojin - The anime is way better, but still the manga is pretty good, same story after all :P
